Specification of Letters Patent.

Application inea January 22, 1915. serial No.'s,791.

To all whom t may concern.'

Be it known that I, HENRY W. HALLEY, a citizen of the United States,residing at Hutchinson, in thc county of Reno and State of Kansas, haveinvented certain new and useful improvements in lnsoles, of which thefollowing is a specification, reference being had therein to theaccompanying 'draws ing.

My invention relates to insoles for shoes and has for its principalobject to distribute and hold antiseptic or other material in a shoe insuch manner as to produce maximum effect with minimum waste. jects willsuliiciently appear in the description hereinafter.

In order to attain my object, I provide an insole with small wells orpartial'perfo-y cate their stockings, at least order to prevent unduefriction and heatm rations distributed with approximate uniformitythroughout its upper surface. These wells or perforations are inpractice filled with the desired material. The nature of this materialmay be varied according to relquirements without departing from thespirit of the invention. Thus, an antiseptic powder may be distributedand held without waste in the little wells, or plain talcum, orsoapstone powder, or grease for pedestrians, or other medicaments ofvarious sorts, dry or not, and it is to be particularly observed thatsince the wells are inthe upper part of the insole and do not extendthrough the material, the medicament is retained where it is needednextthe foot, and does not underany conditions reach the structure of theshoe sole. This is particularly desirable Where a material is employedwhich might soften or rot the. stitching. Itis not unusual for thoseengaged in sports such as golf, or in Walking .for

on the soles, in

y with constant formation of blisters. Obviously, howevenafter the soleof a shoe has been greased in this way and the grease rubbed in,` it canonly be used for purposes requiring grease, and the saine may be said ofmedicaments of any kind. With myI invention on the other hand; the solemay be kept thoroughly lubricated by deposits of grease or medicamentin, the little wells, and if 'it be desired to ruse the shoe afterwardwith different stockings or for a dilerent "purpose, it is onlynecessary to remove the insole which hrings with it all of the grease,

Ancillary obconsiderable periods, to lubril powder, o'r whatnot whichhas been employed.

My invention is illustrated in the accompanying drawings in which-Figure 1 is a'plan view of an insole constructed accordin to myinvention.

Fig. ,2 is a long1tudinal section on the line .7iof F ig. l.

Referring to the drawing, the insole 1 is provided with small wellsorisemi-perfora'- tions 2, which it will be observed are distributedwith approximate uniformity throughout its surface. There are more ofthese perforations under the ball of the foot and directly under theinstep, partly sole and partly is exerted on t the sole.` f

In constructing this insole, the holes may" be pressed or drilled orotherwise produced in a solid body of material such as leather, or asindicated in Fig. 2, they may be' tothe fact that no pressure e sprlngor arch vportion of heel than under the.l due to .the contour of theinmaterial, and not through the other.

In makin a two-part insole, the parts may be punc ed either in two oerations or in one, that is to say either with se arate punches or acombination punch. In t e latter case there will have to be a change inthe tool after the requisite number of rforated layers are produced, sothat the alance of the4 layers will be turned out solid..Y These arethen matched together in pairs, and cemented and stitched or otherwisesecured together, so as to form a solid integral body with the wells-orperforations extending only part way through it.

In practice, powder is'placedi'in a shoe containing this insole and theshoe shaken or moved about to distribute the powder over the insole andthereby fill al the wells. When this has been accomplished, thel sur-I.plus powder may be removed and in yorder I have found that when myimproved insole lis used without antiseptic powder, it has ceri'tainberieicial properties one "owhich is that it appears to afford restto the foot. 'This may partial apertures, which permits ready distribution and evaporation of moisture and vapors. Another beneficialproperty is that the small wells with solid or hermetically closed sidesand bottoms' create suction between the foot and the insole and aord agreater' coefiicient of friction or a greater 'resistance tolongitudinal motion of the foot than an ordinary smooth polished insole.In

`1li walking. with heeledfs'hoesof ordinary construction', 'there is a'tendency for the foot to tbe thrown forward in the shoe with the resultthat pressureis exerted not only latern i ally in acompressiv'e mannerupon the small bones ,of the toes and r -but also rearwardly against thearch of the the ball of'the foot,

", instep; andifisuch pressure maintained, Athat is to say",=1f walking"1s persistedin with Shoes that"` dof not allow free movenientof i 2B thebony arch-of the instep, there will be a.

. t tendency lorth'is' arch to break down,

yducing what is known as "flat foot. This electhas beenvery Anoticeable1n womens heels,`also infmens shes'when the so e due, tosonie`rentilating effect of the position unit.

for the purposes stated, and I contemplate as part of my invention allmodifications of the structure ormethod herein described which fall'airl y within the scope of the appended claims.

'hile I have mentioned leather as a material for my insole, it is to beunderstood that other materials may also be employed without departingfrom the purview of the invention. Among the materials which would hesuitable tov meet general or special conditions I may mention induratedfiber, compressed paper or fabric, andcombinations otl materials,whether in separate layers, each of a single material, or in one com- Asa means` for applying medicaments to the feet, my device may even ishoes' of isome types,` such as lare fitted with varewornJ" Theell'ect'ris' never absent fromv anyshoes having heels, because each stepforw/rd in the rolling motion.l v4of walking,` 23E brings a forwardimpulse t'tlie foot swing- `onkthe ball, while the shoe/is helil haeltbyfction against the ground? It will be l quitebbvio'us/ that a smoothor, polishedl ini sole', especially one which.hasleiinfp(iwdered,

the foot.

40 'letpllsf'itself freely-tothis 'foal-ward tendency o, y p Withmyrinsolefon @the 'con-r,l 1 ft1aiy, itftends' to hold the foot backwhere it belongs, with the heelv resting solidly/'over i theheel of theshoe,the'ai ch over-.the springl or arch of theshoe, and therballiof the/foot on thebroad tread thereof. Ido not broadly lclaim perforationsforthis purpose, as I am' awarethat completely perforated soles havelbeen used fordiferent purposessuch as that of Ventilation. I de claim;hhowever, the use of partial perforations or wellsiin the insole e i beused without a shoe, being bound to the foot in any suitable manner, orit may be provided with heel and toe straps or inclosures, and beuseditself'as a sandal or slipper.

Having thusdescribed my invention what I claimV and desire to `secure byLetters Patent is:

1. An insole having a solid continuous body of substantially uniformthickness provided with a plurality of relatively small depressions orwells with solidly closed sides and bottoms, distributed over thebearing;r surface upon which the users foot will rest, and suliieientlytight and proof against leakage to create suction kbetween the foot andthe. insole, to receive and retain medicaments 9 i `when desired, and toprevent saidmedicaments when employed from passing through the insole. Y

f2. An insole having-a Solid body provided wilh a plurality ofrelatively small depressions pr wells in its upper. side, with solidlyclosed sides and bottoms, said wells being?r filled with antisepticmaterial.

V3. An insole haring a solid body provided with a plurality `ofdepressions or wells in its upper side filled with antiseptic powder.

In testimony whereof I affix my signature s in presence of twowitnesses.
